Application filed May 7, 1919. 'Serial No. 295,363.

. To all whom, it may concern:

Be it knownthat 1, JOHN WoLr, a citizen of the United States, residing at Topeka, in the county of Shawneeand Stateof Kansas, have inventedcertain new and useful Improvements infLocks, of which thefollowing-is a full,'clear, and exac description,

reference bein'g had to the accompanying drawings, forming a part hereof.

provementsin locks, and particularly those employed in connection with wardrobe "trunks for locking one of the hinged sections of thetrunk to the main or body portion, the object sought being to'provide a The present invention is dir ected to im lock with a latch bolt that can be manipulated only from the inside of the trunk to which access is first had by the lifting or opening of a lid which is itself locked to the trunk by. a key-lock of an'y available type. A furtherfobject is to provide a lock which may be either hand-operated, or which may be automatically actuated by the closing movement ofthelid; one which is simple in construction, i reliable, and one possessing further and otheradvantages better apparent from the followingdetailed description in connection with ings in WhiCllf p Figure 1 represents a front elevation of a wardrobetrunk showing one form of my invention applied-thereto; Fig. 2 is anlinside the accompanying drawplan of the lock mechanism detached from the trunk; Fig. 3 isian enlarged longitudinal section through the lock on the line 33 of Fig. 1; Fig. 4 is aside elevation of the lock with parts broken away with the walls of the trunk in section; Fig. 5 is a crosssectional detail on the line 5-5 of i;

Disposed symmetrically on opposite sides of a medial longitudinal line of the plate 4. and directly across the hollow rib 5 are lugs 8, 8, the plate being provided with central opening 0 from which leads a recess O at a point midway between, and adjacent to, the. lugs 8, 8, said recessbeing designed to'rcceive the locking end of the latch-bolt as presently to be more fully de scribed. The opening 0 is bounded by a circular rim 9, thelatter being formed with an offset 9 conforming in contour to, and bounding the recess 0 aforesaid. The leaf 2 is formedwith an inwardly projecting marginal flange a which, when the leaf is closed, snugly engages the? inner Walls of the rib formation 5, 6 (Fig. 3) the free edges of the flange resting against the outer surface of the plate 4. The leaf carries on-its under side acircular housing or casing 10 the wall of which is provided with a cute:

away portion or recess a" at a point opposite the offset 9 of the rim 9 a suitable cup shaped cover or hood ll being passed over the walls of the casing to protect the latch mechanism mounted in the casing and to be presentlyfldescribed. The cover 11;! 1S'pI'O- vided with a cut awayportion orjopening, h almin'gwith the recess 1" of the hous ng"(F1g.

-'9) to permit of the free passage therethrough of the-sliding latch-bolt tofbe presently described. The cup or cover 11 is secured to the walls of the casing why a pin 12 extending diametrically across the chamber of the casing at rightangles'to the path of reciprocation of the-latch-bolt. I

' In the present embodimentof 'my inven- "tion the'latch-bolt 13 (operating through the recess? opening. h, and in the offset 9 terminatesat its'innerendin two arms 14, 14, forming in effect a yoke between whose arms mountedanfexpansion, spring 15 one end 'Of which s-recelved by a socket i at the base ofthe yoke (Fig.' 2), the opposite end being coiled about a pin or stud 16 carried by the wall ofthe casing 10, the tensionof the springtending to force the latch-bolt outwardly or intothe offset 9 of, the rim 9.

The outward movement of the latch-bolt is limited by the, feet or lugs 17 terminating the" yoke arms'14 and projecting outwardly therefrom at substantiallyr1ght' angles thereto, said feet being arrested by the pin 12 when the latch-bolt has been moved the desired distance under the action of the 'spring 15. The feet 17 ride-with their free ends "along theg'inner face of the leaf 2,.said

feetbeing guidedion the sides b'ythe ribs or guides 18 disposed on, the inner face of theleaf 2 and projecting into the chamber of the" casing 10 in which the'latch-bolt and its operating parts are confined. 7

through the opening 0 and its recess 0' The locking member for the latchbolt co1nprises a sliding keeper or plate 19 the same being of a form such as shown in Fig. 8, and

provided with the terminal lugs 20 and 21 respectively, the lug 20 having secured thereto the operating rod or stem 22 gu ded-by suitable straps 23 on' the inner wall of the swinging trunk section T, and terminating at the free end in a finger-holder eye 24:, to which access-is had-by the opening of the lidL of the trunk, the lid being locked by a key-leck .25 of any approved type as well understood in the art.

v ithe keeper plate 19 comprises the portions cl, 6, offset from one another (Fig. 8), the portion cZpperati'ng as the keeper proper. It will be observed that the walls of the "offset9' of the rim 9 do not contact with the inner face of the plate it, but areseparated therefrom'by ajslit or passageways to allow for the free sliding movement there: "through ofthe p ortionfcl of the keeper plate.

"By moving'the keeper sulficiently fto' withdraw thefportion cl thereof from opposite the l ocking fterminal of the latch bolt, the latter isleft free to pass through the recess" 0" (and hence through the opening TO) thereby permitting thejleaf' Qfto sWjng open under theacti'on of the'flexied spring-3.. To eflect release of the latch-bolt the keeper 19 vmust be moved sulficiently to the cross edge if of theportijond 8) past the side of there'cess' Q toward which the merit being indicated r by the arrow adj acent the rod 22 inFig. 2i The mounting forthe sliding keeperplate is as followsg The' lu fgs 8, 8, are embraced bylthe bent terminals-or edge of i which is' providedwith a tongueior lip, 28 bent at right angles to the strip (Fig.

[The tongue 28 is originally stamped in the plane with the strip27 and subse- 'que'ntly bent into the positionld'escribed, the V unfolded position of the tongue being shown 1 dotted in Fig. 9 .The lugs 8, 8, and terminal arms 26, of the strip 27 are traversed keeper is'being moved, thefdirection of movearms 26 of a plate or metal strip 27 one by a pin or stem 29 by which the strip is secured to 'said lugsythe stem passing freely through the lug 21of the keeper 19- and SGIVIHQ; as a guide therefor.

the stem 29 is an expansion spring 30 one end of which bears a'gainst'the inner face of the lug 21 of the keeper 19',the opposite end bearing against the adjacent lug S as a fixed abutment (Fig. 2). The spring 30 tends to force the keeper in proper direction to bring theportion (Z thereof opposite-the recess 0' andhence preventthe latch-bolt 18 from swinging outwardly; and as long as the latch-bolt can not swing outwardly. the spring 3 can not force the leaf 2 to open Coiled about t 7 1 position to permit the parting of the section T of the trunk from the section T the latch- "bolt being carried; by said leaf 2.-
